Err, not quite, actually.

The solution presented below will simply generate the cartesian product of the sum of attributes from the table.

The (grossly pedantic) solution is:

select distinct a.col1, a.col2, a.col3||b.col3||c.col3 from fred a, fred b, fred c
where a.col3 = 'A'
and b.col3 = 'B'
and c.col3='C'

... which really begs the question - 'what IS the question?' ! Although this solution works, it would be quite impractical to apply it to 'test' if there were 'n' values of col3.

Imran - try framing your question in general terms.

Assume your table is name fred:

select a.col1 a.col2 a.col3||b.col3||c.col3 from fred a, fred b, fred c;

Hi,
